Description
Technical field
The invention belongs to bearing inner races to quench field, especially a kind of Double-conical-surface bearing ring bore quenching inducer.
Background technology
Existing bearing inner race quenches mode as shown in Figure 1, technical process：1）First inductor 9 is used to complete 7 epicone of bearing inner race
Face quenches；2）Secondary clamping bearing, then complete the conical surface under bearing inner race with inductor and quench.Defect existing for existing inductor：
1）Part needs clamping twice；2）Need two sets of toolings；3）Part needs 180 ° of overturning, mechanical action to realize that difficulty is big；4）The
Quadric cone quenching easily causes to be tempered to first time quenching area.
Invention content
The present invention provides a kind of Double-conical-surface bearing ring bore quenching inducers, and solving existing inductor cannot be primary
The problem of completing bearing inner race quenching.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of Double-conical-surface bearing ring bore quenching sense
Device, including induction hardening transformer, bus-bar, water spray box, the front end of cylinder manifold is answered to be connect with induction hardening transformer, water spray box is fixed on remittance
On the tail end for flowing row, it is characterised in that：The tail end of bus-bar is equipped with upper arc coil and arc lower coil, and upper arc has
Magnetizer is equipped on effect circle and arc lower coil, upper arc coil and arc lower coil are respectively used in heating bearing
Two conical surface up and down of circle.
Above-mentioned technical proposal is further limited, the upper conical surface of the periphery and bearing inner race of the upper arc coil
It is set in parallel, the periphery of arc lower coil and the lower conical surface of bearing inner race are set in parallel, and can make bearing inner race in this way
The conical surface rapidly and uniformly quench.
Advantageous effect：The present invention can once complete the bearing inner race conical surface up and down using setting up and down two fan-shaped inductors
Quenching, to simplify technique, reduce production cost, ensure that quenching quality.
Description of the drawings

Specific implementation mode
As shown in Figures 2 and 3, a kind of Double-conical-surface bearing ring bore quenching inducer, including induction hardening transformer 1, confluence
Row 2, water spray box 3, the front end of cylinder manifold are connect with induction hardening transformer, and water spray box is fixed on the tail end right side of bus-bar；Institute
The tail end for stating bus-bar is equipped with upper arc coil 4 and arc lower coil 5, on upper arc coil and arc lower coil
It is equipped with magnetizer 6, upper arc coil and arc lower coil are respectively used to two conical surface up and down of heating bearing inner race 7.
Above-mentioned technical proposal is further limited, the upper conical surface of the periphery and bearing inner race of the upper arc coil
It is set in parallel, the periphery of arc lower coil and the lower conical surface of bearing inner race are set in parallel, and can make bearing inner race in this way
The conical surface rapidly and uniformly quench.
Operation principle：Bearing inner race 7 moves up in tooling 8 after clamping, and as shown in Figures 2 and 3, upper arc coil is under
Arc coil is located in bearing inner race；Tooling drives bearing inner race to move horizontally, and as shown in Figure 4 and Figure 5, two coils arrive
Up to heating location, tooling drives bearing inner race rotation, coil to heat bearing inner race, water spray box water spray after the completion of heating
Quenching；Tooling drives bearing inner race to move horizontally, and as shown in Figures 2 and 3, two coils is made to be located at initial position in bearing,
Tooling drives bearing inner race to move down, and takes out workpiece.
Do not elaborate place in this specification, belongs to the common sense of this field.
